Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8148, here are decompositions:
- 31 + 8117 = 8148
- 37 + 8111 = 8148
- 47 + 8101 = 8148
- 59 + 8089 = 8148
- 61 + 8087 = 8148
- 67 + 8081 = 8148
- 79 + 8069 = 8148
- 89 + 8059 = 8148
Showing the first eight; more decompositions exist.
